i IMPROVEMENT IN RAJLROADC EEA-T235.

To allwl'zom. 'it may concern.-

' VBe it known that I, WILLIAM H. BEM., of the city of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Oar- Heateis; and I do hereby declare the following to be a full, clear, and exact description of .the saine, refer-- 'improvement as it is attached.

. The. object of my invention is to secure the heating of a railroad-car, in such a manner as v shall'he at the salue time simple, effective, and safe..

I accomplish this .by introducing, underneath the car, a heater, of any desired shape,coi1strncted, arranged, and held in position substantially as hereinafter set forth.

In the-accompanying drawings, the saine letters refer to like parts.

B B, lig. 1,- is a heater, or furnace, of appropriate form, strength, and size, fastened to thebottom of the car A A, by means of ilanges-h h, on the iron top H H, as seen in fig. 3.

These dan ges rest in iron sockets, or lugs, h', on cach side of the bottom of the car, formed by a continuation of the iron bottom H', covering the bottom of the car,and securely fastened to it, above the furnace.

Between the ends of .the anges h h and inner part of tbe sockets It', are stifil spiral or other kind ci springs, II, which serveto lessen the jarring of the furnace, but the main 'object of these springs is, in case of accident, a collision, cr other catastrophe, in which the cars are injured, to permit the heater 'to detach itself from .the ear, in 'the niaiuier hereinafter set forth, thus rendering it diicult, .if not impossible, for the cars to catch fire from this source. The furnace B issuppliedwith' a pipe, F, for the induction of cool air into .the chamber F', which surrounds the tire-box B', and with a smoke-stack, G, to carry oli the smoke. Both these pipes run upwards,

through the roof of the car, and are covered with tire- :proof felting.

4'.lhe furnace, or at least that part of it nearest the car, is covered with. thesame material.

C is'an opening in the fioor of the car, directly over the furnace, used to introduce fuel into the latter.

This opening has the iron cap, or cover, O', upon.

the upper surface ofthe car-door, and'upon the lower side of the valve, or horizontal door, C, held in position and worked by means of the wire-joiutcd rods, or hooks, to he' nl ulc of wire sutiiciently strong only to 'I retain the valves, or horizontal doors, c, in. position, whilel the heater is attached to the-car, but which will readily straighten out, or part, upon the heater coming loose.

' The sides of this opening muy be protected from iire hy au iron -or other metal thimble, extending `from the cap C to the plate, or door, O".

clined downward toward their ends, forming a central ridge, as represented in figs. 1 and 3.

die D, may be made to clear the ashes from. the heater, in addition to its .regular work of furnishing a draught to the fire.

not prevent the handle D from drawing through the floor, in case the heater becomes detached, as, for 1nstance, by packing the aperture in which the handle D passes, so that the fi'iction will hold it, with the weight of the damper, at any desired elevation, but-in such a manner as that any unusual train or sudden jar willv cause it to operate as stated.

E E are the pipes conveying hot air from chamber elsewhere along the line of the pipes.'

The manner of operation is as follows:

-Cihe fire is kindled in. the fire-chamber B'. Coal or wood is fed in, byvmeans of thecap'O, and the horizontal door C" held in position vby the jointed rod c.

In case of accident, a collision, or of the cars running od' thetrack, a sudden lateral shock, or heavy jar, or the rst concussion caused by the heater B striking the ground, which it is calculated to do the moment the wheels leave the mils, (or all the causes) serves to detach the tlanges it from their position in the sockets 7i', freeing the heater from the cars. Thus all the lire is thrown'away from the cars with the heater, thereby preventing the possibility of great -destruction of property, and of life, from coniiagration, as "iu many cases where other heating-apparatus are used.

Having thus described my invention,

. g What I claim as new, and for which I desire to sscure Letters Patent, is

ygeneral mode of .attachment of the heater to the car, substantially as set forth.

2. The rod D, the horizontal doors, or valves, O", 'and the wire rods or hooks c, constructed and oomstantially as and for the purposes set fort-h.

The ahove specification of my invention signed by me. this 10th day of November, A. D. 1868.
